According to some traditions, women who live under Grandmother Moon’s light will tend to ovulate on the full moon and menstruate on the new moon. In our community of women, we have found that cycles are easier and more harmonious if they follow the cycles of Grandmother Moon in this way. When menstruation falls on the new moon, bleeding does not seem as heavy. Ovulation on the full moon seems most natural.
Because we are surrounded by so much artificial light, even while sleeping, it can be a challenge to get in tune with the moon’s cycles. Research shows that women’s cycles normalize when artificial light is eliminated while sleeping. Artificial light while sleeping appears to interfere with the production of melatonin, which is a hormone associated with ovarian activity. (14)
Women report being able to gradually harmonize their cycles with the cycles of Grandmother Moon by sleeping in total darkness, except for one or two nights at the time of the full moon. If you want to try sleeping in darkness, make some dark shades for your bedroom windows and make sure there is no light of any kind from your clock radio, from under your door, etc.
For one night during the full moon, open your shades and sleep in the moon’s light. If this is not possible, get a night light and use it only during the night of the full moon. You may have to continue this practice for some months, so be patient. You may enjoy seeing your cycles gradually respond to Grandmother Moon’s light.
